Still getting LE-51 after all the fixes

[Shibii]

Hey guys, I still get the LE-51 Error even after all the fixes. I think my account is stuck in a state, because I never got pass the choose a display name, since I got the game on the 9th and am a new player. I tried all the tricks we can think, from verify integration of the files, to reinstall, reboot, turn off cloud on steam, etc.

Here’s a screenshot:
Login to LE

Also here is the error in the Player.log file:

Did you try this one yet?

[LE-51] a unknown error occured

I think I solved the problem, it worked for my account at least and I can pick up where I left off. The topic here helped me a lot and I saved my character from the database again. I did as follows; First of all, I downloaded the game save files from this link [Sign In] and then C:\Users.…\AppData\LocalLow\Eleventh Hour Games\Last Epoch\Saves I made a backup of the Saves folder in the directory and deleted its contents. Then I copied and pasted the backups I downloaded from the link above…

that one was for ppl that played the game prior to update 0.9, i bought the game on march 9th. I still did try it though on that very same day still no sign from my ticket and no one seems to have an answer even when the devs are replying to me on discord or reddit, im clueless lol… 11 days with a game i cant even open.
